Some quotes from various places:
"I've been rich, and I've been poor, and believe me, rich was better." Movie about grifters.
"You can't eat money."
"Money is the root of all evil and all good."
"I have found it easier to teach a seminar on sexuality than on money" (Louise L Hay)
Attitude is what makes the difference. Appreciation of money mixed with fear leads to greed and hoarding.
